The Code
It takes up slots 1-4 in the party for pokemon Platinum. Whenever you can get it done, I'll be very grateful. Thanks!
EvanDixon, can you link me to the Driver download for the NDS cable on Windows 7? Thanks.

So here's the deal. I have Windows 7, and there is no NDS cable driver on it yet. So I can not transfer codes from the Action Replay Manager onto the Action Replay. I have Pokesav and all, and have the code all ready. I would be extremely grateful to anyone who could put in the code and transfer me the 6 pokemon. I have a few legit shinys for trade is it is any incentive. Thanks in advance!
